WINDOWFSASH.

SPECIFICATION forming part of Letters Patent No. 223,342, dated January 6, 1880.

Application filed November 2G, 1879 g patented in Great Britain, November G, 1879.

To all whom it may concern Be it known that l, GEORGE HARTIG, of Brixton, in the county of Surrey, England, have invented certain new and useful Improvements in Window- Sashes, (which invention was patented in Great Britain, November 6, 1879, No. 2,25l,) of which the following is a specification.

"This invention relates to an improved construction of the joints between window-sashes and their casings, its object being to prevent rattling and secure water-prooi' and air-tight joints between the sashes.

The invention consists- First, in the combination, with the grooved jambs of a window-frame and the sashes sliding in said grooves and having their meetingrails provided with beveled meeting faces and their vertical edges provided with rabbets decreasing in width or tapering toward the meeting-rails of said sashes, of tapering battens arranged against the lower ends of the inner walls of the lower sash -grooves, and others against the upper ends of the outer walls of the upper sash-grooves,and each havi ing its smaller end iirnily secured to the adjacent wall, and suitable springs arranged between the end walls andthe wider ends of said battens. By having the smaller ends of the battens rmly secured said battens are prevented from moving longitudinally, while the springs keep the larger ends pressed snugly There is no need to press the narrower ends of the battens against the sashes, asthe latter are, by the action of the inclined faces of the meeting rails, forced against the battens.

Second, the combination, with the grooved lower sash-jamb and the rabbeted sash sliding in the grooves and having its lower edge beveled and provided with a down wardly-projecting lip or extension of its outer portion, and a sloping sill corresponding to the bevel ofthe lower edge of the sash and having a longitudinal shoulder to iit behind the lip of the sash, of the tapering battens arranged against the inner walls of said grooves and having their upper and narrower ends secured firmly thereto, and the springs interposed between said walls and the wider lower ends of the battens. The lip of the sash, fitting over th e shoulder of the sill, prevents rain and snow from beating under the sash, and the springs behind the battens cause the lower end of the sash to be always forced outward, so that the lips will slip beyond the shoulder without striking and abrading its edge.

In the accompanying drawings, Figure 1 is a vertical section of a window-casing, showing an inner view of the jamb. Fig. 2 is a vertical edge view of the upper sash, and Fig. 3 is a similar view of the lower sash. Fig. 4 is a detached perspective view of one ofthe tapering battens.A Fig. 5 is a horizontal sect-ion through the middle of one side of a windowframe. Fig. 6 is an enlarged inner view ofthe lower portion of a jamb, with a tapering batten in position and resting against a spring.

rlhe letter A designates the jamb, and b and c the grooves for thenpper and lower sashes, respectively, these grooves bein g separated by the parting-bead d. i

At the upper end and against the outer wall of the upper sash-groove, b, is secured a downwardly-tapering hatten, D, which lits snugly into a similarly-shaped rabbet, E, in the edge ofthe upper sash, F, Fig. 2, when the latter is in position in its groove.

In the lower end and against the inner wall of the lower sash-groove, c, is arranged an n pwa-rdly-tapering batten, G, which lits snugly into a similarlyshaped rabbet, H, in the edge of the lower sash, I, when in position. The smaller end of each hatten is iirmly secured to the adjacent wall by a screw or other suitable mea-ns, to prevent longitudinal displacement of the hatten.

Both joints of the frame are provided with taperingbattens, and both edges of each sash are rabbeted, as described, and behind the wider end port-ion of each hatten, and between it and the groove-wall, I arrange a spring, J, which keeps it firmly pressed against the sash. Along the inner face of the meetingrail of the upper sash is secured a beveled strip, K, the face of which inclines downwardly from the sash; and along the outer face of the meeting-rail of the lower sash is secured a similar beveled strip, K', inclinng in the opposite direction. The inclined faces ot' these strips cause the meeting ends of the sashes to be forced against the battens, so

IOO

that there is no necessity of springs behind the small ends ofsaid battens, and they are therefore permitted to be firmly seeured.

rIhe lower edge of the lower sash is beveled, as shown at l, Fig. 3, and is provided with a downwardly-projecting lip or flange, m, which, when the sash is drawn down to its lowest portion, takes in front ot' and fits against a shoulder, n, formed on the bottom rail or sill of the frame.

Now, when the two sashes are in their respective groovesand the upper pushed to its highest and the lower to its lowest position,

e .i the tapering battens,fittingin the rabbets, act

as wedges to force the sashes toward eaeh other and snuglv against the parting-bead d., thus forming a very close jamb-joint, while at the same time the faces of the beveled strips K and K', coming together, also exert a wedging action upon each other, and form a snug joint between the two sashes. The close join ts thus formed absolutely prevent vibration and conseqnent'rattling of the sashes, while the lip m, taking over the shoulder n, prevents the passage of rain under the lower sash.

The springs J, as will be readily observed, press the tapering battens toward the sashes, and compensate for wear of the faces of said battens.

The battens, if desired, may be faced with felt or a similar packing'.

The sashes and frame may be equipped with cords, weight-s, and pulleys in the ordinary manner.

I am aware that tapering battens have been arranged to iit into rabbets in the edges of sashes, and that these battens have been faced with rubber and Yprovided with springs; and I do not claim such construction and arrangement, broadly.

What I claim isl. rIhe combination, with the grooved jambs and the rabbeted sashes sliding in said grooves, and having their meeting-rails provided with beveled meetingfaces, of the tapering battens having their smaller ends secured to the walls of said grooves, and the springs interposed between said walls and t-he larger or wider ends of said battens, substantially as described7 and for the purpose set forth.

2. The combination, with the grooved lower sash-jamb and the rabbeted sash sliding in the grooves, and having its lower end beveled and provided with the downwardly-projecting lip, and a sloping sill corresponding to the bevel of the lower edge of the sash and having the longitudinal shoulder to fit behind the lip of the sash, of the tapering battens arranged against the inner walls of said grooves and having' their upper ends secured thereto, and the springs interposed between said walls and the rwider lower ends of said battens, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand in the p resence of the subscribing witnesses.

GEORGE HARTIG.
